摘要： PURPOSE:To make a complex wave dissipating effect securable through a relatively simple structure by erecting a Y-shaped vertical plate, expanding wide along the passing direction of an incident wave, on a horizontal plate being set up under the water surface, and constituting a wave dissipating unit thereat. CONSTITUTION:Plural numbers of wave dissipating units 10 constituted of a horizontal plate 12 being set up under the water surface and a Y-shaped vertical plate 14 being erected on this horizontal plate 12 in projecting one part on the water surface, are set up side by side with a support structure 16. In this horizontal plate 12, one end at the side of an incident wave X is formed into a semicircular form in a state of being set up, while the vertical plate 14 is made up of a base 14a on a straight line to be situated at the side of the incident wave X and a V-shaped part 14b leading to the rear of the base 14a. In addition, the base 14a is tightly installed on a longitudinal axis of the horizontal plate 12, while this V-shaped part 14b is tightly installed on the horizontal plate 12 so as to expand the interval width gradually along a passing direction of the incident wave X.

摘要： PURPOSE:To increase wave dissipation performance and reduce cost by arranging an offshore structure and a coastal side structure approximately in parallel to a shore line and in two rows, and constructing each structure as a bottomless permeable type. CONSTITUTION:Foundation mounds M and M are formed at a certain distance on a sea-bed foundation approximately in parallel to the shore line of a coast, using riprap or the like. In addition, an offshore structure 12 and a coastal side structure 14 constituted with a permeable bottomless cellular box body 22 are arranged on the mounds M. Then, the height A of the upper edge of the structure 12 is set approximately at a level forcibly dissipating a design wave. On the other hand, the height B of the upper edge 18 of the other structure 14 is set at a level between the aforesaid height A and the limit height exceeded by the design wave. According to the aforesaid construction, the structures 12 and 14 can be economically constructed even at a deep sea area, and efficient wave dissipation can be ensured, so long as the sectional form of the structures 12 and 14 are respectively made rectangular.

摘要： PURPOSE:To increase wave breaking effect of a wave by forming a bag body with a flexible material, filling this bag body with fluid so as to obtain a flexible mound, and anchoring the bottom of this bag body on the viscous ground formed on the surface layer part of the foundation ground. CONSTITUTION:A flexible mound 1 is generally constituted by a bag body 2 and a fluid 3. And the bag body 2 is formed with an upper sheet 2a and a bottom sheet 26 of a material such as a vinyl chloride sheet or the like, and the upper part is held in the upward bent convex shape and the bottom part is held flat in the state filled with the fluid 3. Next, a viscous ground 5 whose surface part has been improved with viscous soil is formed on the seabed ground G, and the bottom part 2b of the flexible mound 1 is anchored to the viscous ground 5 with an anchor 4. By this, though arrival of a wave deforms the bag body 2. it is transmitted to the viscous ground 5 through motion of the fluid 3 and dissipated into the ground G by this viscosity resistance, and a wave breaking effect can be obtained.

摘要： PURPOSE:To reduce the cost as well as to facilitate the erection by providing a vertical wave damping bank wherein a wave passing region and a serging space region are integratedly set on the upper part of one or several lines of steel cell structure installed in the water. CONSTITUTION:A structure formed of a plurality of steel cells 10 driven in the water in a line or several lines with a required distance is provided thereon a vertical wave damping bank 7 wherein a front wave passing bank region 1 and a rear serging space region 2 are monolithically formed. On this region 1, X-shaped wave flowing-in/dispersing holes 6 are, for example, formed so as to prevent wave W goes through the region 2 directly. As a result, the energy of the wave W is damped at the branch/integration process of water in the region 1, and the remaining energy is absorbed at the region 2.

摘要： PURPOSE:To permit short-time construction works of steel cell type wave breaker having an excellent wave breakability and high stability, by fitting a precast concrete box, which defines a water chamber inside thereof and has slits on the front side, into a cylindrical steel cell. CONSTITUTION:A cylindrical steel cell 10 is held in place such that the lower part thereof is partially buried into the sea bottom. A packing material is charged into the cell 10 up to a level of the bottom of a water chamber 14. A precast concrete box member 11 having vertical slits 12 on the front side is insertedly placed within the cell 10. A space behind the box member 11 which constitutes the water chamber 14, is further filled with the packing material. A side face of the steel cell 10 is cut to form vertical slits corresponding to those of the box member 11. This enables high efficiency construction works of the wave breaker.

摘要： PURPOSE:To certainly prevent a slip of a offshore structure by setting it on the sea bottom by way of injecting a delayed hardening concrete into a bag body attached to the bottom base of the offshore structure and by hardening the concrete after press-fitting the bag body inside irregular dents on the sea bottom. CONSTITUTION:A bag body 3 is constituted of a film material such as flexible rubber, canvas or vinyl chloride. Then, the bag body 3 is attached to the lower face of a bottom base 21 of a offshore structure to set on the sea bottom through a bag body fitting 1, a space surrounded by the inner surface of the bag body 3 and the bottom base 21 is formed, and a concrete pressure-filling pipe 6 is communicated through to the inside of the space. Subsequently, after pressure-filling delayed hardening concrete 7 and filling it in the bag body 3 from the press-fitting pipe 6, the offshore structure is set on the sea bottom. Then the bag body 3 of concrete 7 in the state where it is not hardened is press-fitted in irregular dents on the sea bottom surface or a rubble-mound or others under the weight of the offshore structure, and as the concrete 7 is hardened, the bag body 3 can be fixed on the sea bottom in conformity to the irregular dents of the sea bottom.

摘要： PURPOSE:To increase wave breaking effect of a wave by forming a bag body which is bent upward with a sheet of a flexible material, filling this bag body with fluid so as to make it in the convex shape, and dividing the inside of this bag body up and down with a film body having a large number of holes. CONSTITUTION:A flexible mound 1 is generally constituted by forming a bag body 2 with a flexible material and by filling it with fluid 3 such as sea water, water or the like. And the bag body 2 is formed by a material such as a vinyl chloride sheet and its bottom sheet 2b is held flat and its upper sheet 2a is held in the shape of an upward bent convex. Then, a transparent film body 5 having a large number of holes 4... such as sponge or the like is mounted on the inner surface of the upper sheet 2a so that the inside of the bag body 2 is divided into up and down. By this, when a wave arrives at the flexible mound 1, the fluid 3 flows and passes the holes 4... of the film body 5, a turbu lent flow is generated, and energy is damped and wave breaking effect of the wave is increased.
